10:57 am include migration (+ selection) in hwce treatment for population genetics migration, genetic drift, biased mating - greater prairie chicken. The numbers of populations have decreased over time. 1962, sanctuaries were set up to protect them. And then lots of farmland was set up which was detrimental to the birds. 1970s and then decreased migration - one-island model. Imagine migration from continent to island is much greater than vv -- assume all are homozygous for a1 allele on the continent and all are homozygous for a2 allele on the island. Bio 3ff3 page 1 (makes two populations more similar) If allow migration to continue in both directions, we"d expect populations to be similar. Gene pool of island population in yellow, gene pool of continent in blue. If we allow individuals to mate on island, they will only produce the same alleles. migration - allele frequencies migration - homogenization.

The time period I chose is the 1960âs. When President Kennedy came into office the country had just been through here recessions; one from 1953 to 1954 after the Korean War, one from 1957 to 1958, and one in 1960. The Kennedy administration recognized the implications such recessions had on the economy and felt a more aggressive approach would be necessary. By 1962, the economy was beginning to sputter. The growth rate of real GDP was 7.1% in 1959 but decreased to 2.5% and 2.3% in 1960 and 1961, respectively.

The Kennedy Tax Cut Plan, which was proposed in 1962, however, did not take effect until after his assassination in 1964. For households, tax withholding rates decreased from 18% to 14%, leading to an estimated tax reduction of about $6.7 billion. Taxes on corporations were also decreased; the reduction in taxes for 1964 was expected to be about $1.7 billion. By 1965, the economists expected that taxes would be lower by $11billion. In 1965, nominal GDP was about $719 billion, so these changes were about 1.5% of nominal GDP.

True or False

Not only is the share of the GDP going to health care higher in 2012 than in 1929, the wages of health care workers have risen more rapidly than for other types of labor.

Of the 1,750 students expected to graduate with an M.D. from U.S. medical schools this year, the average debt per student will exceed $100,000.

Capitation is the most common form of hospital payment received from managed care organizations.

The idea that hospital competition has led to a âmedical arms raceâ can help explain why the U.S. has more than twice the OECD average number of MRI machines per 1,000,000 population.

U.S. health spending per capita in 2012 was

a)less than $3,000.

b)between $3,000 and $5,000.

The Principle of Diminishing Marginal Returns means

a)the more a good is consumed, the lower the average benefit from consumption.

b)the more of a good that is produced, the greater the benefit of the last good to the supplier.

c)the less of a good that is produced, the greater the average productivity of inputs.

d)The more of a good that is produced, the lower the productivity of the last input to production.

e)the more of a good that is produced, the greater the marginal productivity of the last input.

The primary costs to be accounted for in health care projects include all of the following except:

a)Medical care, follow-up and administration.

b)Treatment damages (side effects).

c)Reductions in future medical costs.

d)Time and pain of patient and family.

e)Provider time and inconvenience.

c)between $5,000 and $7,000.

d)between $7,000 and $9,000.

e)more than $9,000.

patient cost sharing is now a permanent feature in almost all health insurance contracts. The insurers introduce patient cost sharing with the goal to

a)reduce adverse selection.

b)reduce risk aversion.

c)reduce consumer demand.

d)increase consumersâ medication compliance.

e)use those funds to guarantee full coverage of catastrophic events.

The Beaverdam Run Condominium Association (the âAssociationâ) is a not-for-profit association set up to manage the condominium. Owners of condominium units elect the Board of Directors to make the Associationâs decisions on their behalf. The Associationâs Lighting Committee has presented a proposal to the Board of Directors. The Associationâs responsible for maintaining the street lights. All such lights are currently incandescent bulbs. The proposal is to remove all the existing incandescent flood lights and replace them with compact fluorescent (âCFLâ) flood lights. The CFL flood lights are more expensive to purchase than the incandescent flood lights have been, but the CFL flood lights would consume less electricity. Specifically, the data offered by the Lighting Committee is as follows:

Type of Flood Light	Purchase Cost	Annual Electricity Usage
Incandescent	$3.30	$28
CFL	$5.32	$6

CFLs last longer than incandescent bulbs, but, for this question, assume that both incandescent flood lights and CFL flood lights last an average of one year. The Lighting Committee has proposed that it replace all the incandescent flood lights with CFLs at once. Two of the Board members have objected that it would be wasteful to discard the incandescent flood lights that are currently installed, as they still have up to a yearâs life left in them before they would burn out. Suppose that you are a member of the Board of Directors.

Assume that the incandescent lights that would be replaced have no resale value, so they would be discarded if they were replaced. Would you vote to replace all the existing incandescent lights with CFL flood lights at once, or would you replace the incandescent flood lights over the next year as they burn out? Show your calculations of costs of the two alternatives, and explain the reasoning of your conclusion
